Letters Patent No. 88,219, dated March 23, 1869.

IMPRO'VED SINK.

The Schedule referred to in these Letters Patent-and making part of theIlma.

To all whom it may concern Be it known that we,WILLIAM SEAMAN andGEonGEA. BANTA, of the city and State of New York, have invented, made, andapplied to use, a certain new and useful Improvement in Sinks; and we dohereby declare the following to be a f'ull, clear, and exact descriptionofthe said invention, reference being had to the annexed drawing, makingpart of this specification,l

wherein- Figure lis a plan of' said sink, as separated from thewood-work, and

Figure 2 is a vertical transverse section, the woodwork being shown inred lines.

Similar' marks of reference denote the same parts.

Sinks heretofore made, and adapted to being surrounded by a woodencasing, have had a flange projecting around the upper edge, to passbeneath the wood-work.

From the shrinkage ofthe wood,.there is an opening quickly formedbetween the metal sink and the wood-work, into and through which wat-ersplashes, and this is particularly the case at the back part of thesink; and from the moisture and drippings, the oor below is constantlysaturated, and frequently rots.

The nature of our said invention consists in a groove around the fiangeofthe sink, with return-channels into the sink, so that the water thatsplashes in between the fiange and wood-work will run back into thesink;and at the back we form a vertical flange, at the edge of' thehorizontal flange, so as to set up behind the vertical back casing ofthe sink.

We have shown our invention as applied to a square sink, but it may beused upon corner and half-circle low water that splashes in between thewood-work and the flange to run back again into the sink.

e is a vertical flange, on the edge ofthe ange d, at the back of thesink.

f is the front, and g, the horizontal casing of Woodn work enclosing thesink; and

h. is the wood-work at the back, extending up agains the wall, andbehind which the flange c sits, so that any water that splashes againstthe wood-work h will run back into the sink, instead of' soaking andsplashing down between the wood-work and horizontal flange d, asheretofore, and wetting the wall or floor, or both.

The strainer-plate usually employed over the wastewater pipe is fiat, ornearly so; hence all floating substances, such as tea-leaves,potato-skins, oto., are washed into the strainer, and clog up theopenings. To prevent this, we make a cavity, i, in the bottom of thesink, and employ a dome-shape strainer, k, so that any foreignsubstances may pass into the eavityz', and the upper part of thestrainer remain free for water to run away.

The dome-shaped strainer contains more area for thc reception ofperforations than a flat strainer.

What we claim, and desire to secure by Letters Patent, is-

1. The metallic sink, formed with the grooves 3 and Vchannels 2, in thefiange d, and the back flange e, upon the edge of the flange (l, as andfor the purposes set forth.

2. The metallic sink, formed with the cavity c', and dome-shapedstrainer lc, as and for the purposes set forth. s y

I n witness whereof, we have hereuntoset our signatures, this 25th dayof April, 1868.

WILLIAM SEAMAN.
